bead weld

基本解釋

Bead weld, thermal spray coating, electroplating and brush-plating are the main recondition techniques of the metal parts in mechanical equipments.
機(jī)械設(shè)備中金屬件的修復(fù)技術(shù)主要有：堆焊、熱噴涂、槽鍍和電刷鍍。
Localized heating from the welding process and subsequent rapid cooling induces welding shrinkage stresses along weld bead during welding thin-wall plate and causes structural buckling distortions.
在薄板焊接中，由于局部加熱和迅速冷卻產(chǎn)生了沿焊縫方向的焊接收縮應(yīng)力，而導(dǎo)致焊接薄板發(fā)生屈曲變形。
Thiscondition can occur in any weld bead depression, but it is more likely to occur in the end of abead, especially a tack weld .
該情況可能發(fā)生在任何焊珠凹陷中，但其最可能發(fā)生在焊珠的末端，特別是點(diǎn)焊。

堆焊
Compared with traditional surface technologies (plasma spraying, bead weld, etc. ), it has low heat input, deformation and rate of dilution.
與傳統(tǒng)的表面技術(shù)(等離子噴涂、堆焊等)相比,它具有熱輸入少、工件的變形小、稀釋率低,熔覆層與基體材料的界面結(jié)合為冶金結(jié)合,同時(shí)熔覆層的凝固速度快,得到的熔層晶粒細(xì)小;熔覆層的耐磨損、耐腐蝕性能優(yōu)于傳統(tǒng)技術(shù)加工的涂層性能。
